The graffiti seemed to refer to the internment without charge -- known as administrative detention -- of three alleged Jewish extremists in the wake of a July 31 arson attack in the West Bank village of Duma that killed 18-month-old Palestinian Ali Saad Dawabsha and his father Saad.

Locals said Israeli forces and police arrived to the area, investigated the incident, and dusted for fingerprints at the scene.

On Wednesday, Israeli forces had closed the Ein Samiya area road and prevented Palestinians from using it.

Recent weeks have seen a rise in Israeli settler attacks against Palestinians in the West Bank.

An 18-month-old Palestinian, Ali Dawabsha, was burned alive when alleged Israeli extremists firebombed their home at the end of last month in the village of Duma near Nablus.

The toddler's father, Saad Dawabsha, succumbed to his wounds a week later, after suffering third degree burns on 80 percent of his body.

On Saturday morning, Israeli settlers attacked a Palestinian home with firebombs and rocks in an area east of Tayba in the Ramallah district. The bombs landed outside of the house, causing no damage, locals told Ma'an.

Israeli settlers have carried out at least 120 attacks on Palestinians in occupied East Jerusalem and the West Bank since the start of this year, according to the UN Office for the Coordination of Humanitarian Affairs.
